Just received and I'm impressed with the auto detection of 6 or 12 volt batteries, along with showing the recharge percentage. It signals a full charge with a beep and a bright light, which stays on while in trickle charge status. The power cord is a bit short (about 2.5 ft.), but worked where I wanted the charger near a wall outlet. The length of the battery line is generous (almost 6 ft.) The battery clamps are a bit flimsy feeling, but hopefully they hold up.

This item is.Complete trash I bought this To charge my Lithium ion Phosphate P04 Battery. It is a 12 v 50 ah Battery.Upon read upon receiving the battery at three pm on Monday February tenth I connected The positive crocodile clip to the positive terminal then proceeded to connect the negative to the negative terminal. Set the mode for the charger as lithium-ion. Upon plugging into outlet, it showed the battery was 12 V and at 75% charge. I did my math to find out that there was still 30% more to go. So I divided 30% from 3, which gave Me Eleven hours I started at three pm It is now 3 AM in the morning. So I did some more research and digging found out it.With only needing 30% more charge, it would have took me 4 hours to charge instead of 11. It has been 15 hours.I am very frustrated and can not contact the seller to find out what I am doing wrong. I get that you can hook it up backwards but connecting. The negative terminal to the negative charge and deposit of charge to the positive terminal. Is pretty much self-explanatory, especially when you read The manualNow I know my battery is. Not in sleep mode because I have A light bulb in a desktop Computer conneci did to the inverter. I can drain power out, but it will not charge.Which leave me to believe either the battery's defective and a highly doubt. The battery is defective because. I'm able to discharge the battery. So I would really appreciate if the seller would at least create a video explaining how the charger works in dethel. Obviously you have a mode button which switches between lead acid in lithium. But it says, if the battery is not connected correctly that the lithium or whatever mode you have it on would flash as well. As the battery indicator. Which is which is confusing. There's no diagram on the manual showing which 1's the battery indicator there's 3 lights which would be the little battery icon with the percentage from.25 50 75 and a 100. Percent.Then on the right, you have a 12 V and 6 V battery light and at the top you have lead Acid lithium In repair mode but no diagram explaining Is the battery indicator?Like I said, trash, most stuff that sell on Amazon. If it's electronic, come with a Diagram

A very good product that recharges my automotive battery during the car is storage for winter. It is smaller and lighter than those heavy chargers on the market. Very stratified so far. Also, the delivery box looks nice and protected:)

Just changed my car battery. Got this to fully charge it. It took couple of hours to charge it from 75% to 100%. It automatically stopped after charging.

We don’t drive very much these days, and that can take a toll on a car. Our old battery began having trouble maintaining a charge, and our mechanic recommended picking up a trickle charger. This YHCHKJ charger has a nice set of features for the price, so I was eager to test it.It’s much smaller than I expected, but I appreciate that the majority of functions are automatic. There are three modes (lead acid, lithium/ LiFePO4, and Repair), as well as a number of protections built-in. It comes with two sets of leads (clamps and washer ends), and I really like that the charge indicator that shows the current battery level while charging.That said, the plastic construction doesn’t seem especially strong. The clamps feel quite brittle, and it wouldn’t surprise me to see the handles crack before long. If you’re gentle with them it will probably be okay, though. The manual is also quite disappointing. You’ll learn far more by watching the video on the listing than you will from reading that.Pros:-Small and lightweight-Easy to use; most functions are automatic after you select the battery type-Two sets of clip-in leads included (clamp and washer)-Three modes with automatic voltage recognition-Repair cycle is nice to have, though I can't comment on its effectiveness-Charge indicator is helpful-Built-in protections against short circuit, over-temp, over-voltage, reverse polarity, etc.Cons:-Manual isn’t very detailed; better off watching the video on the listing to see how it works-Plastic construction feels a bit light-Clamps feel brittle, so be gentle if possibleThis isn’t quite as robust as I hoped, but it’s a perfectly good little charger for the price and I'm very pleased with it.My rating: 4 stars

J’ai reçu le chargeur mais dans la petite feuille instructions (anglais seulement) il n’y a aucune mention au sujet de la garanti, la durée etc. Aucune mention , rien.
